!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

sys-apps/hwids:0

(sys-apps/hwids-20121119::gentoo, ebuild scheduled for merge) pulled in by
(no parents that aren't satisfied by other packages in this slot)

(sys-apps/hwids-20121217::gentoo, installed) pulled in by
>=sys-apps/hwids-20121202.2[udev] required by (sys-fs/udev-196-r1::gentoo, installed)

virtual/udev:0

(virtual/udev-171::gentoo, ebuild scheduled for merge) pulled in by
=virtual/udev-171 required by (sys-fs/eudev-0::gentoo, ebuild scheduled for merge)
(and 1 more with the same problem)

(virtual/udev-196::gentoo, installed) pulled in by
=virtual/udev-196 required by (kde-base/kdelibs-4.9.3::gentoo, installed)
>=virtual/udev-180 required by (sys-fs/udev-196-r1::gentoo, installed)
(and 16 more with the same problems)

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Ist eudev jedoch maskiert sieht das ganze so aus:

Code:

slap ~ # emerge --newuse --update --deep --with-bdeps=y -av world
